Make Ahead Grilled Brats and Beer Wisconsin Style

READY IN: 1hr 35mins
Recipe by Always in the kitch

These are great to make ahead for cookouts or tailgating. Especially if you need the grill for other foods. They can be reheated in a foil pan on the grill, in the oven or in a crock pot. They can be made a day ahead, the morning of, or served right away. You need fresh bratwurst for this, not the smoked or white colored sausage. We've already made 100 of these ahead for large groups.

This is a GREAT way to prepar brats! I made these as part of our 4th of July barbeque buffet and everyone loved them. The beer gives the brats a wonderful flavor and onion-loving DH was in onion heaven! :) I especially like the fact that these can be made ahead of time- more time to mingle with friends. Thanks for posting this, Connie- it's a winner!
